摘要：

We study the propagation of the light mesons sigma, omega, rho, and a(0) (980) in dense hadronic matter in an extended derivative scalar coupling model. Within the scheme proposed it is possible to unambiguously define effective density-dependent couplings at the Lagrangian level. We first apply the model to study asymmetric nuclear matter with fixed isospin asymmetry, and then we pay particular attention to hyper-matter in beta-equilibrium. The equation of state and the potential contribution to the symmetry coefficient arising from the mean-field approximation are investigated.
